Service HotlineIn the design of modern aviation and aerospace vehicles, in order to reduce weight and save space, the space of the fastening installation system is getting narrower and narrower, and blind hole installation is often required. In this case, single-sided riveting installation is usually used for fastening connection. At present, this kind of fastening connection products are mainly blind rivets. The riveting installation principle of blind rivets is to use the method of pulling, pulling the mandrel, and extruding the nail sleeve to deform it at the blind end to achieve the function of fastened connection. This kind of fastening connection method requires special riveting, generally imported riveting, the replacement of internal parts is expensive, the installation process is complicated, and the installation cost is high.
The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a low-carbon steel rivet nut fastener, which can be easily fixed on a thin wall without welding, easy to operate, firm riveted, and suitable for single-sided riveting.
safety screw includes a screw rod, and is characterized in that: the two ends of the screw rod are respectively provided with notches for rotating a tool knife. Compared with the prior art, the advantage of Guangdong Yueluo Hardware Industry Co., Ltd. is that notches are provided at both ends of the screw, so that when the screw is in use, it can be tightened or loosened from both ends without installation. Due to the limitation of position and structure, when the installation space is small or the tool knife cannot be inserted, it is convenient for the operator to directly tighten or loosen the screw from the other end, which improves the efficiency of installation and disassembly, saves assembly time and reduces assembly difficulty.
Nut fasteners are used in various industries with connection and fastening requirements, such as vehicles, construction machinery, agricultural machinery, manufacturing machinery, etc. For large construction machinery or construction vehicles, due to the harsh working environment and the action of heavy loads, the nut fasteners on it are subjected to vibration and load impact in all directions, which makes the nut easier to loosen, resulting in tightening. The function of the device is reduced or even failed. cause a great safety hazard.
Building aluminum alloy formwork is a new type of building formwork, which conforms to the four sections and one environmental protection policy. It is economical, fast, high-quality and environmentally friendly. Its application is of great significance to building energy conservation and environmental protection. The aluminum template is filled with aluminum template pins. However, the pins in the prior art have low connection strength during use, which is likely to cause the hole to be repaired weakly.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: six-star head screws, cylindrical pins with holes, nickel-plated nylon self-locking nuts, inner multi-washers and other products, we can provide you with products suitable for you fastener solutions.
